Two dirty old porcelains . An early Canadian cent marked white porcelain and another appears to me to be the same, unmarked and possibly even earlier production as it's got a side seam. (two piece mould ? dry process? ) [id=451053435]

Elton Gish - The white insulator with the cent mark is U-610A. Two others have been reported as well as several others in brown or reddish brown. The white glaze is a much more uncommon to rare color. I continue to show it, but it is also cataloged as U-2542 in the foreign numbering system.
